How much does it cost to hire a business broker in Canada?
Business brokers in Canada typically charge 8–12% commission on transaction value for small business sales. Most brokers work on a success-fee-only basis — you pay the commission when the business sells, not before.
Success Fee Commission Structure
Success-fee-only arrangements are the predominant pricing model for business brokers handling transactions under $5 million. The broker earns their fee only when the sale closes.
Brokers commonly charge minimum fees of $10,000–$25,000 to ensure compensation on smaller transactions. A $100,000 business sale at 10% would generate $10,000 in commission, while a $50,000 sale would trigger the minimum fee rather than a $5,000 commission.
Business broker commissions are subject to GST/HST as a taxable professional service. The broker remits GST/HST on top of their commission, which the seller pays.
For larger transactions, M&A advisors typically charge success fees of 2–10% of transaction value, declining with deal size. The Lehman Formula structures success fees as 5% on the first $1M, 4% on the second $1M, 3% on the third $1M, 2% on the fourth $1M, and 1% on amounts above $4M. According to the M&A Source Middle Market Report 2023, commission structures may be negotiable, particularly on larger transactions where a lower percentage rate can still yield substantial dollar compensation.
Upfront Retainer Fees
Some business brokers charge an upfront retainer of $5,000–$25,000, typically deducted from the closing commission. This retainer offsets the broker's initial costs for valuation, marketing materials, and buyer outreach.
M&A advisors handling larger transactions typically charge monthly retainers of $5,000–$25,000 per month during 6–12 month engagements. These monthly fees are separate from the success fee and may or may not be credited against the commission at close.
Additional Costs and Expenses
Sellers typically pay for business valuation reports, legal fees, accounting fees, and marketing expenses as additional costs beyond broker commissions.
Straightforward business valuations typically cost $5,000–$25,000 while complex engagements involving litigation or disputes can cost $25,000–$50,000 or more. The valuation establishes an asking price and provides documentation for buyers.
Legal and accounting fees during the sale process cover purchase agreement review, tax structuring, and financial statement preparation. These costs are separate from the broker's fee.
Fee Variations by Deal Size
Commission rates tend to be higher for smaller transactions and lower for larger deals due to the fixed work required regardless of transaction size. A broker selling a $500,000 business performs similar work to one selling a $5 million business — preparing marketing materials, qualifying buyers, managing negotiations — but the smaller deal generates less commission at the same percentage rate.
This explains why minimum fees exist and why percentage rates decline on larger transactions.
What Affects Total Cost
Broker listing agreements typically include tail provisions of 6–12 months protecting the broker's commission if the seller transacts with a buyer introduced during the listing period. If you terminate the listing and then sell to a buyer the broker introduced, you still owe the commission.
The total cost to sell your business includes the broker's success fee, GST/HST on that fee, valuation costs, legal fees, accounting fees, and any upfront retainer. On a $1 million business sale at 10% commission, expect $100,000 in broker fees plus $13,000 in GST/HST (Ontario HST rate), plus $10,000–$30,000 in combined valuation, legal, and accounting costs — approximately $123,000–$143,000 in total transaction costs.
